Indirect length calculation
The indirect length calculation is intended for determining certain distances using length
measurements to various points and angle measurements of the respective axes.
Indirect length calculation 1
1. Point the laser beam at the first measuring point (A).
2. Press the “Measurement” key.
The measurement is started and the measured value will be
shown on the digital display.
3. Point the laser beam perpendicularly to the surface at the
second measuring point (B).
4. Press the “Measurement” key.
The measurement is started and the second measured value
will be shown on the digital display.
The device calculates the distance between the two
measuring points from the measurements and the determined
value will be shown on the digital display.
/
Indirect length calculation 2 / 3
1. Point the laser beam at the
first measuring point (A).
2. Press the “Measurement”
key.
The measurement is started
and the measured value will
be shown on the digital
display.
3. Point the laser beam at the
second measuring point (B).
4. Press the “Measurement”
key.
The measurement is started and the second measured value will be shown on the digital
display.
5. Point the laser beam perpendicularly to the surface at the third measuring point (C).
6. Press the “Measurement” key.
The measurement is started and the third measured value will be shown on the digital
display. The device calculates the distance between the measuring points A and B from the
measurements and the determined value will be shown on the digital display.
Indirect length calculation 4
1. Point the laser beam at the measuring point (A).
2. Press the “Measurement” key.
The length measurement and angle measurement (in relation
to the horizontal) are started and the measured values will be
shown on the digital display. The device calculates the
distance between measuring point A and the horizontal
perpendicular (with respect to the distance to be calculated)
from the measurements. The determined value will be shown
on the digital display.
/
Indirect length calculation 5 / 6
1. Point the laser beam at the
first measuring point (A,
above the horizontal
perpendicular with respect to
the distance to be
calculated).
2. Press the “Measurement”
key.
The length measurement and angle measurement (in relation to the horizontal) are started
and the measured value for the length will be shown on the digital display.
3. Point the laser beam at the second measuring point (B, indirect length calculation 5: below
the horizontal perpendicular, indirect length calculation 6: above the horizontal
perpendicular with respect to the distance to be calculated).
4. Press the “Measurement” key.
The length measurement and angle measurement (in relation to the horizontal) are started
and the measured values (angle between measuring points A and B) will be shown on the
digital display. The device calculates the distance between the measuring points A and B
from the measurements and the determined value will be shown on the digital display.
Digital spirit level (axis)
The digital spirit level (axis) is intended for measuring an angle of
an axis in relation to the horizontal and for displaying the
corresponding inclination.
1. Place the device flat onto the surface to be checked.
2. Align the device. The axis of the device must correspond to
the axis to be checked.
The measured value will be shown on the digital display and a
digital spirit level indicates the inclination.
In horizontal position, the alignment point (“bubble”) is exactly
between the two markings and will be displayed in green.
Digital spirit level (surface)
The digital spirit level (surface) is intended for displaying an inclination of a surface in relation
to the horizontal.
1. Place the device onto the surface to be checked.
The digital spirit level indicates the inclination. In horizontal position, the alignment point
(“bubble”) is exactly within the inner marking and will be displayed in green.
Stake-out function
The stake-out function is intended for dividing a distance into
previously set subsections of equal lengths.
1. Set the desired length of the subsections.
2. Press the “Measurement” key.
3. Point the laser beam at the measuring point.
4. Press the “Measurement” key.
The measurement is started and the following values will be
shown on the digital display:
- Set length of the subsections (setting)
- Number of subsections with respect to the measured
distance (measured value)
- Measured distance (measured value)
- Yellow arrows on the top and bottom of the digital display: display in which direction the
next complete subsection is located (integer).
5. Reposition the device accordingly.
Press the “Measurement” key to interrupt the measurement and press the “Menu” key to
exit the measuring function.
